I have a feeling it will have less of an effect on my FE than someone who travels shorter distances might experience.

Let's see here:
My metro seems to stay in cold start mode (as Suzuki intended) for about 5-6 miles or 9 minutes of driving time. About 9 minutes until the gage says it's up to full operating temp. My morning commute is 70miles one way, with traffic, 90 minutes. My car is in cold start mode for say, 10% of the morning operating time. I don't know how much additional fuel the designers added when in cold start mode.

With Kat's heater, the time it takes the engine (at least the gage) to come up to full operating temp is reduced to about 1 mile or 2 minutes. About 2% of my drive time is spent in cold start mode.
